Patent DE-19608559-A1 (DE)
Inventor: KNEUPER HEINZ-JOSEF DR
IPC: B01J38/00
Filed: 1996-03-06
Abstract: The invention concerns a process for preparing amines having more than four carbon atoms by simultaneous hydroformylation and hydrogenating amination of corresponding olefins containing one carbon atom less in the presence of at least equivalent amounts of ammonia or a low-molecular amine or polyamine with at least one primary or secondary amino group by means of an unmodified rhodium catalyst dissolved homogeneously in the reaction medium at high pressure and high temperature. The rhodium catalyst is separated out of the liquid reaction mixture by separating the homogeneously dissolved unmodified rhodium catalyst from the reaction medium by means of a magnetizable inorganic pigment which is suitable for the complex or adsorptive bonding of rhodium and is uncoated or coated with a binder. This pigment is separated from the liquid reaction medium after it has been charged with the rhodium present in the reaction medium by the application of an external magnetic field.
Patent DE-19609787-A1 (DE)
Inventor: SENGER KARL-HEINZ DR ING DR
IPC: F16H61/662
Filed: 1996-03-13
Abstract: The invention relates to an emergency hydraulic control system for ratio-dependent changing of hydraulic-oil pressures in a first and a second hydraulic taper-disc axial shift of a continuously variable transmission. In said control system, a pump (1) supplies at least the piston chamber (17) of a second axial shift. A remotely controlled relief valve (50) connected downstream and at least one electromagnetically-operated pressure limiting valve (60) restrict the oil pressure therein. Said pump also uses said supply to feed the piston chamber (13) of a first axial shift and by way of the remote control line (97, 98) a remote control system (leading to the valve (50) and having an opening function) by way of a continuous directional valve (30). Opening of the continuous directional valve (30) to move into the flow position is controlled by the pressure upstream of the valve (60). At least the individual drive conditions such as start-up, forward, reverse and neutral can be selected by corresponding change-over positions of a manually-operated valve (20). Should the actuating electronics fail, then the driver can also use a "low" gear in addition to an "overdrive" gear to drive up slopes.

Title: Recycling process for HDPE fuel storage containers
Inventor: LORENZ ARNULF DIPL CHEM
IPC: C08J11/06
Filed: 1996-11-13
Abstract: In a recycling process for used high density polyethylene (HDPE) fuel containers the containers are cleaned and granulated and the resulting particles fed into a reactor (3). The particles are heated to 120-127 deg C at 0.05-10 mbar pressure and remain in the reactor under these conditions for a given period before conversion into a reusable raw material. Preferably the particles remain in the reactor (3) for three hours at 120 deg C and 1mbar pressure followed by a further three hours at 127 deg C at the same pressure. Particles may be transferred to a second reactor for the second process stage allowing another batch to be simultaneously processed in the first reactor (3). Uniform heating of the particles is effected by a stirrer (4) in the reactor (3) and use of particles of approximately equal size. Stirrer design and rotational speed ensure that frictional energy input does not cause overheating. Fuel vapours from the reactor are drawn off, collected and fluidised. Processed particles extracted from the reactor (3) are melted and granulated for further use.
